.....................................................my favorite optimist doesn't have much good to say about wind power: "As for resource consumption and environmental impacts, the direct effects of wind turbines — killing birds and bats, sinking concrete foundations deep into wild lands — is bad enough. But out of sight and out of mind is the dirty pollution generated in Inner Mongolia by the mining of rare-earth metals for the magnets in the turbines. This generates toxic and radioactive waste on an epic scale, which is why the phrase ‘clean energy’ is such a sick joke and ministers should be ashamed every time it passes their lips." -full post is here
Columbus's good luck lay not in his miserably wrongheaded calculations about distance but in his accurate knowledge of the North Atlantic trade winds, which flow in a great clockwise circle. How he came by this information we can't be sure. It may have been the result of his own observations on his previous voyages, only some of which we know about. In any case, it was information not widely understood at the time, even if in our own day it is common knowledge to transatlantic airline passengers. As a result of his awareness of the trade-winds pattern, he was able to keep them at his back, plotting a southerly outgoing course and a northerly homecoming one, both of which enabled him to travel much more quickly than others had been able to do. In this way, Columbus and his crew were saved from contrary winds, becalmings, and death by dehydration on the high seas.
"Man
finds himself everywhere mirrored in nature. Wayward, inconstant, always
seeking rest, always impelled by new evils, the greatest of which he himself
creates, – protecting and cherishing or blighting and destroying the
fragmentary life of a fallen nature, incapable himself of creating new
capacities, but nourishing in prosperity and quickening in adversity those that
are left, – he sees the workings of his own life in the strife of the elements.
His powers and activities are related to his spiritual capacities, as inorganic
movements are related to an organizing life. The resurrection of his higher
nature is like a new creation, secret, sudden, inconsequent. 'The wind bloweth
where it listeth, and thou hearest the sound thereof, but canst not tell whence
it cometh, and whither it goeth; so is every one that is born of the Spirit.' " -Chauncey Wright, the concluding paragraph to his 1858 essay, The Winds and the Weather
